Abnormal ECG Wave Reference Card – 8 Rare but Vital ECG Patterns with Descriptions

Recognise the subtle signs that could change patient management with this abnormal ECG wave reference card, designed for paramedics, doctors, ECG technicians, nurses, cardiologists and students. This compact visual guide highlights 8 uncommon but critical ECG findings, each accompanied by a waveform visual and a clear description of its appearance.

What’s Included on the Card:

Each abnormal wave includes a visual representation and a concise description of its characteristic ECG appearance, helping you identify and recall these complex patterns quickly and confidently.

- Raised ICP (Cushing’s Reflex)
• Appearance: Bradycardia with bizarre T-waves or deep inversion, often with QT prolongation

- Epsilon Wave
• Appearance: Small positive deflection (‘blip’) at the end of the QRS in V1–V3 (seen in ARVC)

- Massive Pericardial Effusion
• Appearance: Low voltage QRS and electrical alternans (beat-to-beat QRS variation)

- Hypertrophic Cardiomyopathy
• Appearance: Deep, narrow Q waves in lateral leads and giant negative T waves

- Brugada Syndrome
• Appearance: Coved ST elevation in V1–V2 followed by inverted T wave

- Hyperkalaemia
• Appearance: Tall peaked T-waves, widening QRS, flattened or absent P waves

- Wolff-Parkinson-White (WPW)
• Appearance: Short PR interval and a delta wave (slurred upstroke of QRS)

- Sodium Channel Blockade
• Appearance: Widened QRS with prominent terminal R in aVR

Product Features:

- Size: 86mm x 54mm (fits all lanyards and ID holders)
